Well, so far I have no luck locating a nice, sharp example on eBay for a reasonable price. Especially those touted as "Civil War issue!" go for ridiculous high prices. I just checked Heritage and it seems to offer many more better quality specimens for similar prices as eBay.
My feeling is eBay has gone downhill with respect to quality offerings. Also locating high quality Guldens (my other focus) is a problem with overpriced, low quality coins galore.
Yes, I am regularly checking GC as well. In fact I send them some random leftover coins that no longer fit in my collection objectives. I'm curious what they will go for. The coin from your link I have seen before. Looks lightly cleaned to me (even though NGC doesn't mention it). At normal magnification it will probably be just a shiny mirror. Not really interested in that.
